Details
Description
Holosun AEMS CORE X2 Red Dot Sight is the AEMS with the options taken out and the price brought down. One 2 MOA red dot, no reticle menu, no solar cell — but the same large square enclosed window, the same sealed emitter and the same hard-anodised aluminium housing as the rest of the family, with the four-post lower-1/3 co-witness mount still in the box.
How It Compares
For the Multi-Reticle System and Solar Failsafe, step up to the AEMS PRO X2 or the newer-generation AEMS EVO. The same single dot in another emitter colour: CORE Green or Gold. New to co-witnessing, read how to co-witness with iron sights.
Ideal For
- Budget AR-15 and carbine builds
- Shooters who only ever run a plain dot
- Rifles that live outdoors in poor weather
- Lower-1/3 co-witness mounting

Is the Holosun AEMS CORE X2 Red weatherproof enough to leave on the rifle?
